[Java]将一个字符串按照指定字符数进行分割

    public static String[] splitStr(String str, int splitLen) {        int count = str.length() / splitLen + (str.length() % splitLen == 0 ? 0 : 1);        String[] strs = new String[count];        for (int i = 0; i < count; i++) {            if (str.length() <= splitLen) {                strs[i] = str;            } else {                strs[i] = str.substring(0, splitLen);                str = str.substring(splitLen);            }        }        return strs;    }
